Fireclass 516.054.011.YFC MR601TEx Conventional High-Performance Optical Smoke Detector

The MR601TEx detectors react to the whole range of fire products from slow smouldering fires, producing visible particles to open flaming fires producing large numbers of very hot smaller sized aerosols. It combines optical and heat detector technology to detect clear burning fire products which hitherto could only be easily detected by ion-chamber detectors.

For normal ambient conditions, the high-performance optical detector behaves as a normal optical detector. Only when a rapid rise in temperature is detected does the sensitivity of the detector increase and the presence of smoke will confirm a fire condition which will be transmitted as an alarm level.

The MR601TEX overcomes the slower response of optical detectors to hot burning fires by increasing the sensitivity of the optical detector when it is associated with a rapid change in temperature. In this way it is intended to become a detector which will suit some of the risks currently covered by ion chamber detectors. Smoke detectors will not detect burning alcohol or other clean burning liquids which do not generate smoke particles.

The MR601TEx detector is designed to comply with EN 50 014 and EN 50 020 for intrinsically safe apparatus and is certified: to ATEX Code: Ex II 1G and Cenelec Code: EEx ia IIC T5.
